The paper considers carbyne nanostructures as filtering members for separation of gas mixtures based on selective adsorption of its components, in particular, hydrogen, helium and methane. The size of a highlyselective cell is determined in this paper. It is found that the number of layers in carbyne membrane has no effect on the selective separation of gas mixtures.

Urban areas often face significant flooding challenges due to impermeable surfaces that exacerbate stormwater runoff, making effective stormwater management essential. This study demonstrated that combining pervious concrete pavement systems with underground aggregate storage beds and rain gardens can significantly enhance water infiltration and drainage efficiency, providing valuable insights for designing low-impact development strategies in flood-prone regions.
